What are the components of a pin header connector? Introduction to pin header connectors.

8 月 16, 2023 通过 admin 0 评论

Pin header connectors are commonly used with socket connectors to form board-to-board connections or with terminal connectors in electronic wire harnesses to form board-to-wire connections. They can also be used independently for board-to-board connections. These connectors are primarily composed of contacts, accessories, insulators, and housings.

1.Contacts:

Contacts are the essential components of the connector and consist of male and female contact pairs. The electrical connection performance of pin header connectors relies on the mating of these male and female contacts. The male contacts are rigid components and can be cylindrical, rectangular, or flat in shape. The female contacts, known as receptacles, utilize an elastic structure that allows for resilient deformation when male pins are inserted. This elastic deformation generates spring force, ensuring a secure and close contact between the male and female parts to establish the connection.

2.Accessories:

 This category includes structural components and installation accessories. It comprises retaining rings, keying options, locating pins, guide pins, coupling rings, cable clamps, sealing rings, sealing gaskets, and other structural attachments. Installation accessories such as screws, nuts, bolts, and spring rings are also part of this category.

3.Insulators:

Also referred to as bases or mounting plates, insulators are responsible for arranging the positions and spacing of the contacts as required. They ensure the insulation performance between the contacts and between the contacts and the housing. Insulators need to possess excellent insulation resistance, voltage withstand capabilities, and ease of processing.

4.Housing:

The housing not only provides protection but also ensures the precision during insertion. It securely fastens the connector to the device.

Performance of connectors

8 月 6, 2023 通过 admin 0 评论 ,

Connectors have three fundamental performance categories: mechanical performance, electrical performance, and environmental performance. The emphasis on connector performance varies across different fields.

Mechanical performance refers to the ability of a connector to function properly under various mechanical forces. Important mechanical performance factors of connectors include insertion force and withdrawal force. Insertion force refers to the force required for insertion, while withdrawal force refers to the force required for extraction. Mechanical lifespan refers to the durability of the connector and is determined by whether the connector can maintain its functionality after a specified number of insertion and withdrawal cycles.

Electrical performance refers to the ability of a connector to maintain its proper functionality under different current and voltage conditions. It mainly includes contact resistance, insulation resistance, withstand voltage, and electromagnetic interference shielding effectiveness. Other electrical indicators for connectors such as RF coaxial connectors include characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio. For high-speed signal connectors, new electrical indicators such as crosstalk, transmission delay, and time delay have emerged.

Environmental performance refers to the ability of a connector to operate normally in various environmental conditions. Common environmental performance factors include temperature resistance, humidity resistance, salt spray resistance, vibration resistance, and shock resistance. Other environmental performance factors include sealing capability, resistance to liquid immersion, and low-pressure resistance.

Why do connectors need to have metal plating? What materials are used for metal plating?

8 月 5, 2023 通过 admin 0 评论

Most connectors are coated with a layer of metal plating, and there are two main types of plating materials: gold and tin. Gold is representative of a precious metal coating that is less susceptible to oxidation in the air. Tin is representative of a non-precious metal coating material that is more prone to oxidation or sulfidation in the air.

Among these two materials, tin plating is more common as it is cost-effective and has a relatively soft texture. However, it has a lower lifespan in terms of the number of plugging and unplugging cycles and can only provide basic protection against corrosion. If a connector product requires a higher number of plugging and unplugging cycles, gold plating is typically used.

Coating the surface of connectors with this layer of metal serves two main purposes:

Corrosion Protection: Corrosion maintenance is a primary concern for connectors. Nowadays, most electrical connectors have contact springs made of copper alloys, which are highly susceptible to corrosion in typical operating environments. The contact plating is applied to create a barrier between the contact springs and the operating environment, thus preventing corrosion of the copper.

Improved Electrical Performance: One of the key requirements for electrical connectors is to establish and maintain a stable connector impedance. To achieve this, a metal contact interface is needed to provide inherent stability. Establishing such a contact interface requires a thin surface film that can either avoid or break during contact mating. These two different options highlight the distinction between precious or rare metals and common metals.

Introducing I-PEX’s High-Temperature Connector Products

8 月 3, 2023 通过 admin 0 评论 ,

I-PEX offers high-temperature resistant products that can be guaranteed to operate at temperatures up to 105℃ and 125℃.This article introduces the product series best suited for each application that requires high-temperature resistance.

I-PEX offers high-temperature resistant products that can be guaranteed to operate at temperatures up to 105℃ and 125℃.

In recent years, high heat and high vibration resistance were important for connectors used in automotive and industrial equipment, but these characteristics have also become increasingly important in consumer equipment as well, while equipment and systems have become smaller and more sophisticated. One example is “Mini-LED” backlight technology, in which several thousand micron-sized miniature LEDs are arranged on a highly transparent glass substrate for use in LCD TV backlighting. Compared to conventional LED backlights arranged on printed circuit boards, Mini-LEDs are more efficient, brighter, and have a longer life span. However, the large number of LEDs required and the large number of electronic components densely packed in the control area raise the ambient temperature, leading to an increase in overall heat density. Therefore, connectors must have sufficient heat resistance.

This article introduces the product series best suited for each application that requires high-temperature resistance.

I-PEX ZENSHIELD® connector transmission MIPI’s camera module signal

8 月 3, 2023 通过 admin 0 评论 ,

The era of epidemic greatly changed people’s lifestyle. With more and more people at home, there are more and more opportunities for online meetings and talks. Therefore, people have also changed dramatically for the performance of electronic equipment.

In particular, many of the latest laptops have enhanced the camera function to meet such needs, and more and more are equipped with high -definition cameras and infrared cameras for facial recognition.

The signal transmission from the camera module to the motherboard generally uses USB, but with the improvement of the camera resolution, many cases have been used to use the MIPI CSI-2 D-PHY, and its communication speed is faster than USB. In the past, the MIPI signal that needed to output the camera image sensor was converted into a USB signal inside the camera module for transmission.

MIPI CSI-2 D-PHY V2.1 supports the transmission speed of up to 4.5 Gbps per channel, which is much faster than the traditional USB 2.0. Traditional USB 2.0 supports up to 480 Mbps per channel. However, in the laptop and tablet, various electronic components are densely installed, and the antenna is often installed nearby. The MIPI signal (including the D-Phy system clock signal line) may adversely affect the antenna. Therefore, EMC measures are very effective for preventing signal interference between them.

  1. PEX Zensheild® connector series can provide excellent EMC countermeasures. The 360 -degree EMC shielding design can not only prevent electromagnetic noise radiation from the contact point of the public and female seats, but also prevent electromagnetic noise radiation from the board installation part (SMT position) from the signal terminal. In addition, when the connector is embedded to correct the correct ground to the circuit board, the mask and the mother seat shielding layer is correctly connected to connect at multiple points. This ensures that the current generated in the metal shielding layer of the connector has sufficient grounding path. This can inhibit electromagnetic noise from its shielding layer.

Design of ZenSheild® connector series

1. The entire connector is covered with 360 ° shielding, used for public seats and mother seats -not only the contact part of the signal terminal, but also the board installation part (SMT position).

2. The shielding interface between the public seat and the mother seat is effectively connected on multiple points.

3. In addition, multiple points of the interface of the connector shielded to the board are correctly grounded on the board, thereby improving the ground return path.
